Potential First Client, Don't Want To Blow It! Need Advice.

Hi Everyone!
This is my first post after reading all the great advice on the forum. I need some advice.

On Monday I sent out some emails to local therapist who are on page one of Google but don't seem to be converting visitors into customers based on the information in their websites.

I created a sample ebook based on one or two articles on their site and put a link in the email. I've only sent out 5 emails so far but got an email from one therapist who wants me to call him to discuss the services I provide.

I don't want to start off the conversation listing a bunch of my services. I have a list of questions I plan to ask him about his business and then go from there on which of my services he could really use.

This would be my first client so there is fear about making sure I can deliver. Also, I'm afraid of under cutting myself on how much to charge.

He could use a new website, google places listing and he has a book that he sells through an online distributor that I could turn into an ebook that he can sell on his site. Those are a couple services I can suggest.

My focus is to make sure I offer him value. I need some help on what the monetary value should be for these services.

Thanks for your help!
